Invitiation Limitation per timeframe

I just installed your great plugin, but there is one thing thats missing for me.
I’d like to have a limit for the invitation thats per defined timeframe. Like 7 Invites per Week for each user.

I could add that myself, but that way I would not be able to update anymore. It would be great to see this feature in a future release.
